Other newsletters and books followed in the wake of Ruff's first publication. In 1975, Kurt Saxon began publishing a monthly tabloid-size newsletter called The Survivor, which combined Saxon's editorials with reprints of 19th century and early 20th century writings on various pioneer skills and old technologies. Kurt Saxon used the term survivalist to describe the movement, and he claims to have coined the term.[8]
The survivalist hard-on (yep, and I'll do it again, too) for prophylactics untouched by chemical pleasure-enhancers is the result of drilling deep (told you) into the magical properties of our latex friends. According to our research, these flexible, durable, waterproof wonders will be as much of a deciding factor in your dystopian longevity as fire and can openers.
You now have a foolproof method of navigation and enough light. But you need to sleep and eat. The Gerber Bear Grylls Ultimate pro knife with its full tang 4 ¾” high carbon steel blade is just the piece of survival gear you need to help you harvest materials for an emergency shelter, get a fire started, open cans and if necessary, dress wounds and cut bandages.
I do understand, out of my friends and family I’m the most prepared. I constantly go out to the middle of nowhere and put my skills to the test. Just for argument sake, but what if someone is more equipped than you? What if someone else is better prepared ie: more knowledgeable, more practical experience, time in the field putting skills to use than all others in your group? What then, does it mean that you would sideline someone more equipped mentally than you and all others to lead over your own pride?, Or would you go against what you have said and actually not jeopardize your groups well being and let the more experienced person led. To give your group the best possible chance of survival, or would you possibly condemn your loved ones and friends to a fate of death or even worse over your pride?
Further interest in the survivalist movement peaked in the early 1980s, with Howard Ruff's book How to Prosper During the Coming Bad Years and the publication in 1980 of Life After Doomsday by Bruce D. Clayton. Clayton's book, coinciding with a renewed arms race between the United States and Soviet Union, marked a shift in emphasis in preparations made by survivalists away from economic collapse, famine, and energy shortages—which were concerns in the 1970s—to nuclear war. In the early 1980s, science fiction writer Jerry Pournelle was an editor and columnist for Survive, a survivalist magazine, and was influential in the survivalist movement.[16] Ragnar Benson's 1982 book Live Off The Land In The City And Country suggested rural survival retreats as both a preparedness measure and conscious lifestyle change.
Each type you listed (save a couple) will have its uses in a community (group if you will), generally having a small trusted group with each having several skills in the various fields (prepper, homesteader, and survivalist) I believe would be an effective team, though as each group works together would it not be best to ensure that each has overlapping skills in case of injury, death, or other reasoning they can not fulfill their duties?
Gerald Celente, founder of the Trends Research Institute, noted how many modern survivalists deviate from the classic archetype, terming this new style "neo-survivalism"; "you know, the caricature, the guy with the AK-47 heading to the hills with enough ammunition and pork and beans to ride out the storm. This [neo-survivalist] is a very different one from that".[26]

The Cold War era civil defense programs promoted public atomic bomb shelters, personal fallout shelters, and training for children, such as the Duck and Cover films. The Church of Jesus Christ of Latter-day Saints (LDS Church) long directed its members to store a year's worth of food for themselves and their families in preparation for such possibilities;[2] but the current teaching advises only a three-month supply.[2]

Other small kits are wearable and built into everyday carry survival bracelets or belts. Most often these are paracord bracelets with tools woven inside. Several tools such as firestarter, buckles, whistles and compass are on the exterior of the gear and smaller tools are woven inside the jewelry or belt and only accessible by taking the bracelet apart.
Wetfire is a non-toxic product that won’t produce clouds of noxious smoke. All it takes is a tiny bit sprinkled on the camp stove to get it going even when the rain or snow is coming down in blankets. In survival situations many perish because they’re unable to create the warmth they need to counteract cold, wet conditions. Wetfire is pocket-sized survival gear that allows you to withstand nature’s worst. Wetfire has a 5 year shelf life and can be activated using any stormproof lighter or other sparking device.
This group is concerned with the spread of fatal diseases, biological agents, and nerve gases, including swine flu, E. coli 0157, botulism, dengue fever, Creutzfeldt–Jakob disease, SARS, rabies, Hantavirus, anthrax, plague, cholera, HIV, ebola, Marburg virus, Lassa virus, sarin, and VX.[35] In response, they might own NBC (nuclear, biological and chemical) full-face respirators, polyethylene coveralls, PVC boots, nitrile gloves, plastic sheeting and duct tape.

To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
